<em>sieve tube elements are the cells of phloem which allow transportation of photosynthates through phloem...
<u>
how sieve tube elements form sieve tubes:
</u>sieve tube elements are connected end to end and form a long chain which is called sieve tube,,,,
sieve tube elements are connected with the help of a side chain with the help of peptide bond...also one element has tapering end which easily overlaps with other end of next element to form sieve tube,,,,</em>
In this question, the correct order of flow of energy in an aquatic ecosystem is Phytoplankton → zooplankton → fish → mammal.
<h3>What do you mean by an Ecosystem?</h3>
An environment may be defined as the complex of physical, chemical, and biotic factors (such as climate, soil, and living things) that act upon an organism or an ecological community and ultimately determine its form and survival.
The flow of energy in an aquatic ecosystem depends on the phytoplankton which are known as the producers of an aquatic ecosystem.
Therefore, the correct order of flow of energy in an aquatic ecosystem is described above. Hence, the correct option is B.

It has feet attached to its head. Cephalopod is a Greek word, where cephalo means head, and pod means foot.

The haploid stage of plasmodium I did observe by using the micrograps is what you called a stage of malaria. These red blood cells have been invaded by plasmodium merozoites, a stage of malaria. There are several stage of malaria, The first stage is the stage of infection and the second stage is the sexual reproduction that divide into two; the pre- erythrocytic and <span>erythrocytic phase.</span>
